[0002] A circuit board laser marking machine is a device specifically used for marking circuit boards. The circuit board laser marking machine irradiates the surface of the circuit board with a high-energy laser beam. The energy of the laser beam causes physical or chemical changes in the material on the surface of the circuit board, thereby forming a permanent mark. This mark has the characteristics of high precision, high clarity, and not being easily worn, and is widely used in the production process of circuit boards to mark information such as the model, specification, production date, and serial number of the circuit board, facilitating product traceability and management. Marking on the circuit boards of communication devices ensures the quality and reliability of the devices.

[0003] During the use of the existing circuit board laser marking machine, the circuit board is usually fixed directly below the laser. Fixing can ensure the accuracy of the marking. It enables the circuit board to maintain an accurate position within the working area of the laser marking machine. After being fixed, the position of the circuit board is fixed, and the operator can quickly position and place it, reducing the positioning time, enabling the laser marking machine to operate continuously without frequently adjusting the position of the circuit board, and greatly improving the equipment utilization rate and production speed. After the marking of the previous circuit board is completed, a loading and unloading operation is required, and then the next circuit board is installed. In this way, a relatively long time is consumed in the loading and unloading process of the circuit board, resulting in a significant reduction in the marking rate of the circuit board and making it difficult to meet the requirements of high-efficiency production. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a circuit board laser marking machine to solve the problem that after the marking of the previous circuit board is completed, a loading and unloading operation is required, and then the next circuit board is installed, consuming a relatively long time.

[0007] The abutment comprises a circular segment and an elastic segment, one end of the elastic segment is connected to the circular segment, the other end of the elastic segment is gradually arranged away from the circular segment, and the elastic segment is arranged on a side of the circular segment away from the local gear.

[0008] Furthermore, an annular sliding block is provided at the bottom of the rotating member, an annular sliding groove is provided at the top of the workbench, and the rotating member is rotatably connected to the workbench via the annular sliding block and the annular sliding groove.

[0009] Furthermore, the depth of the placement groove is lower than the thickness of the circuit board.

While one circuit board is being processed, a new circuit board can be installed. The whole process forms an efficient cycle. The driving motor runs continuously, so that each link is closely connected, avoiding unnecessary pauses and waiting, ensuring the continuity of production, greatly reducing waiting time, and improving overall production efficiency.

[0019] The circuit board laser marking machine controls the abutment to intermittently abut the movable clamping block through the driving motor, thereby clamping the circuit board.

DETAILED DESCRIPTION

[0028] The present invention will be further described below in conjunction with the embodiments.

[0029] The following embodiments are used to illustrate the present utility model, but cannot be used to limit the protection scope of the present utility model. The conditions in the embodiments can be further adjusted according to specific conditions. Any simple improvement to the method of the present utility model under the premise of the concept of the present utility model belongs to the scope of protection required by the present utility model.

[0030] Please refer to Figure 1 、 Figure 2 and Figure 6 , the present utility model provides a circuit board laser marking machine, which includes a workbench 10. A connecting frame 110 is arranged on one side of the workbench 10, and a laser 30 is installed on the connecting frame 110.

[0031] Please refer to Figure 1 、 Figure 2 、 Figure 6 and Figure 7 , a rotating member 20 is rotatably arranged on the top of the workbench 10. An annular slider 210 is arranged at the bottom of the rotating member 20. An annular sliding groove 101 is opened on the top of the workbench 10. The rotating member 20 is rotatably connected to the workbench 10 through the annular slider 210 and the annular sliding groove 101, and the rotating member 20 is annular.

[0032] A plurality of placing grooves 201 are opened on the top of the rotating member 20. The plurality of placing grooves 201 are symmetrically arranged around the center of the rotating member 20. The depth of the placing groove 201 is lower than the thickness of the circuit board 40. The circuit board 40 can be placed in the placing groove 201, which can play a role in limiting the circuit board 40 for the first time and avoiding tilting when the circuit board 40 is clamped and fixed.

[0033] Fixed clamping blocks 230 are connected to each of the plurality of placing grooves 201. An active clamping block 120 is arranged above one of the placing grooves 201. The active clamping block 120 is movably arranged left and right on the connecting frame 110. Two connecting rods 130 are horizontally connected to the right side of the connecting frame 110. A connecting block 140 is connected to the top of the active clamping block 120. The connecting block 140 is movably sleeved on the two connecting rods 130. The connecting rods 130 are in a T shape, which can prevent the active clamping block 120 from disengaging from the connecting rods 130; an elastic member 150 is arranged between the connecting block 140 and the connecting frame 110. The elastic member 150 is sleeved on the connecting rods 130; by pushing the active clamping block 120 to move left, the circuit board 40 is clamped in cooperation with the fixed clamping block 230. When the active clamping block 120 moves left, the active clamping block 120 squeezes the elastic member 150 through the connecting block 140 to store energy. When the thrust on the active clamping block 120 is cancelled, the active clamping block 120 returns to its original position under the action of the elastic member 150, and the fixing of the circuit board 40 is cancelled.

[0034] Please refer to Figures 1-7, a bottom of the rotating member 20 is connected with an internal gear 220. A driving assembly is arranged inside the ring of the rotating member 20. The driving assembly includes a driving motor 510, an engaging driving member 520 and a resisting member 530. The driving motor 510 is installed inside the workbench 10, and an output shaft of the driving motor 510 penetrates out from the top of the workbench 10. Both the engaging driving member 520 and the resisting member 530 are installed on the output shaft of the driving motor 510, and the resisting member 530 and the engaging driving member 520 are arranged vertically. A partial gear is arranged on a side wall of the engaging driving member 520. The engaging driving member 520 can be meshed and connected with one side of the internal gear 220 through the partial gear. By driving the engaging driving member 520 to rotate through the driving motor 510, the engaging driving member 520 intermittently drives the rotating member 20 to rotate through the internal gear 220.

[0035] The resisting member 530 and the movable clamping block 120 are on the same horizontal plane. The resisting member 530 includes a circular section 531 and an elastic section 532. One end of the elastic section 532 is connected to the circular section 531, and the other end of the elastic section 532 is arranged to gradually move away from the circular section 531. The elastic section 532 is arranged on a side of the circular section 531 away from the partial gear; when the partial gear on the engaging driving member 520 cannot be meshed and driven with the internal gear 220 (as Figure 5 shown), then by driving the resisting member 530 to rotate clockwise through the driving motor 510, as the distance between the elastic section 532 and the circular section 531 increases, the elastic force of the elastic member 150 is less than the elastic force of the elastic section 532, which will cause the elastic section 532 to resist the movable clamping block 120 to move leftward to cooperate with the fixed clamping block 230 to clamp the circuit board 40 (as Figure 2 shown). When the elastic section 532 rotates subsequently, since neither the movable clamping block 120 nor the circular section 531 can move, it will cause the elastic section 532 to move closer to the circular section 531 until the elastic section 532 passes by the movable clamping block 120 (as Figure 3 shown). When the output shaft of the driving motor 510 rotates again, the partial gear on the engaging driving member 520 and the internal gear 220 drive the rotating member 20 to rotate (as Figures 3-5 shown).

[0036] The working principle and usage process of the present utility model: Place the circuit board 40 in the placement groove 201, and drive the engaging driving member 520 to rotate clockwise through the driving motor 510. The engaging driving member 520 intermittently drives the rotating member 20 to rotate through the internal gear 220 (as Figures 3-5As shown, each rotation of the rotating member 20 is the angle between two adjacent placement grooves 201; when the meshing driving member 520 fails to drive the rotating member 20 to rotate, the driving motor 510 still drives the abutting member 530 to rotate clockwise. As the distance between the elastic section 532 and the circular section 531 increases, the elastic force of the elastic member 150 is less than the elastic force of the elastic section 532, which will cause the elastic section 532 to abut against the movable clamping block 120 and move leftward to cooperate with the fixed clamping block 230 to clamp the circuit board 40 (as Figure 2 shown). At this time, processing is performed by the laser 30, and at the same time, a new circuit board 40 is installed. After the elastic section 532 passes through the movable clamping block 120 (as Figure 3 shown), a cycle is completed.

[0037] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
